Abstract
The utility model provides a sphere screw, comprising a nut, a gasket, a screw rod and a screw head, wherein the screw head is arranged below the screw rod, the lower end of the nut is provided with the gasket, a connecting piece is arranged between the gasket and the screw rod, a baffle is arranged between the screw rod and the screw head, the periphery of the screw rod is provided with threads, a groove is arranged in the middle of the connecting piece, and the outer ring of the nut is a sphere. The utility model aims to design the sphere screw, due to the arrangement of the groove, the flexibility of the screw is improved, and the impact of the screw is absorbed; and due to the arrangement of the baffle, the screw is more stably fixed after being fixed without swinging back and forth.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of sphere screw.
Background technique
Fastening piece, also referred to as standard piece, is that two or more parts (or member) are fastenedly connected the general name that becomes class mechanical parts that adopt when whole on market.Its feature is that description is various, and the performance purposes is different, and standardization, seriation, unitized strong.Fastening piece is most widely used mechanical basic part, is in great demand.
Each components of traditional screw does not have enough strength and stabilities, usually occurs the phenomenon that comes off after set screw, causes machine service life to be affected.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of sphere screw, groove the pliability that has improved screw is set, absorb the impact of screw, the setting of baffle plate makes after set screw to be unlikely back and forth and rocks, and makes screw fixing more stable, this model utility is simple in structure, and easy to use.
The utility model provides a kind of sphere screw, described sphere screw comprises nut, pad, screw rod, and the screw head that is arranged on described screw rod below, described nut lower end is provided with pad, be provided with link between pad and screw rod, be provided with baffle plate between screw rod and screw head, in the screw rod periphery, be provided with screw thread, described link middle part is provided with groove, and described nut outer ring is sphere.A kind of sphere screw of the purpose of this utility model design, groove the pliability that has improved screw is set, absorb the impact of screw, the setting of baffle plate makes after set screw to be unlikely back and forth and rocks, make screw fixing more stable, this model utility facilitates the mounting box dismounting, and the Security that screw connects is good.
The utility model discloses a kind of a kind of improvement of sphere screw, the width of described baffle plate equates with the width of pad.The width of this improvement baffle plate equates with the width of pad, and purpose improves the serviceability of screw, extends its working life.
The utility model discloses a kind of a kind of improvement of sphere screw, the cross section of described groove is the indent rectangle.The cross section of this improvement groove is the indent rectangle, has improved the pliability of screw, absorbs the impact of screw, reduces maintenance man's engineering time.
A kind of sphere screw of the purpose of this utility model design, groove the pliability that has improved screw is set, absorb the impact of screw, the setting of baffle plate makes after set screw to be unlikely back and forth and rocks, make screw fixing more stable, this model utility facilitates the mounting box dismounting, and the Security that screw connects is good.
